Political Systems, Regimes, and Governments

  • A state requires a defined territory, a permanent population, a government, and sovereignty; a regime is the set of rules and norms governing who holds power and how.

  • Regime types are distinguished by three dimensions: degree of pluralism, degree of state autonomy from society, and the balance of coercion versus consent in rule enforcement.

  • Authoritarian regimes typically restrict civil liberties, lack competitive elections with real turnover risk, and concentrate power in an executive not accountable to a legislature.

  • Democratic regimes require competitive elections, rule of law, protection of civil liberties, and civilian control of the military; procedural democracy alone does not guarantee liberal democracy.

  • Regime change differs from government change: a new cabinet under the same constitutional order is a government change, while a new constitutional order is a regime change.

  • Failed states lose effective monopoly on the legitimate use of force; indicators include loss of territorial control, inability to collect taxes, and dependence on foreign aid.

  • Illiberal democracy holds elections but limits civil liberties, media independence, or judicial review; hybrid regimes combine authoritarian and democratic features.

  • Supranational organizations (e.g., the EU) transfer some sovereignty upward, so state sovereignty is not absolute in practice.

Political Institutions

  • A parliamentary system fuses executive and legislative power: the prime minister is selected by and accountable to the legislature, and can be removed by a no-confidence vote.

  • A presidential system separates executive and legislative power with fixed terms; divided government occurs when the executive and legislative majority come from different parties.

  • A semi-presidential system has both a directly elected president and a prime minister responsible to the legislature; executive power is shared and can produce cohabitation.

  • Unicameral versus bicameral legislatures: bicameralism adds a second chamber that may represent regions (federal systems) or serve as a revising body.

  • Judicial review is the power of courts to invalidate laws conflicting with a constitution; it may be strong (concrete and abstract review) or weak (limited to concrete cases).

  • Federal systems divide sovereignty between national and regional governments with constitutional protection; unitary systems delegate power but can revoke it.

  • Electoral systems structure institutions: single-member districts with plurality rules favor two-party systems, while proportional representation tends to produce multiparty coalitions.

  • Executive term limits and election rules shape institutional stability: fixed terms reduce turnover risk but can produce lame-duck periods.

Political Culture and Participation

  • Political culture is the set of attitudes, beliefs, and values about politics; it is distinct from public opinion, which is specific and changeable.

  • Almond and Verba's typology: parochial (little awareness of government), subject (aware but passive), and participant (aware and active) cultures.

  • Political socialization agents include family, schools, media, religious institutions, and peer groups; family and schools are typically the earliest and strongest.

  • Forms of conventional participation: voting, campaigning, contacting officials, joining parties or interest groups; unconventional participation includes protests, boycotts, and strikes.

  • Voter turnout is shaped by electoral rules (compulsory voting raises it), registration requirements, and the perceived competitiveness of elections.

  • Civil society organizations mediate between citizens and the state; a dense associational life is associated with stronger democratic accountability.

  • Social movements use collective action outside formal institutions; their success often depends on framing, resources, and political opportunity structures.

  • Political efficacy (internal and external) measures whether citizens believe they can understand and influence politics; low efficacy correlates with low participation.

Party and Electoral Systems and Citizen Organizations

  • Duverger's law: single-member plurality electoral systems tend to produce two-party systems; proportional representation tends to produce multiparty systems.

  • Proportional representation allocates seats by share of the vote, often with a threshold; it increases minority representation but can fragment parliaments.

  • Mixed-member systems combine district and list seats, allowing voters to split their ticket between a candidate and a party.

  • Party systems are classified by number of effective parties: dominant-party, two-party, and multiparty; effective number is measured by the Laakso-Taagepera index.

  • Catch-all parties seek broad appeal and moderate positions; cadre or elite parties rely on narrow networks; mass parties rely on large memberships.

  • Interest groups differ from parties: they seek to influence policy rather than contest elections, and may use lobbying, litigation, or collective action.

  • Pluralist interest group systems feature many competing groups; corporatist systems institutionalize bargaining among a few peak associations and the state.

  • Electoral rules affect representation: single-member districts create a personal vote and constituency service, while closed lists emphasize party loyalty.

Political and Economic Changes and Development

  • Modernization theory links economic development (income, education, urbanization) with the emergence of democratic institutions; it is correlational, not deterministic.

  • Dependency and world-systems theories argue that peripheral economies are structurally disadvantaged by core economies through trade and capital flows.

  • Import substitution industrialization (ISI) protects domestic industry through tariffs and quotas; export-oriented industrialization targets foreign markets and is associated with East Asian growth.

  • Neoliberal reforms (privatization, deregulation, trade liberalization) are often conditions attached to IMF or World Bank lending.

  • The Human Development Index combines life expectancy, education, and income; it measures development more broadly than GDP per capita.

  • Political development indicators include rule of law, corruption control, government effectiveness, and accountability; these are distinct from economic growth.

  • Resource curse: economies dependent on natural resource exports often show slower growth, weaker institutions, and higher corruption.

  • Globalization increases trade, capital flows, and migration; it constrains state economic policy but also creates new transnational actors.
